Take a video of any TWO team members both completing a successful bottle flip at exactly the same time. Each person should be flipping their own standard (16 ounces or so) bottle of water onto a hard surface, and getting it to successfully remain standing upright once it lands. The bottle can be filled with as much water as needed to improve your chances of completing the challenge successfully. What will make this challenge difficult is getting two people to make a successful flip on the same attempt. Your entire team can all be attempting the challenge together, as long as any two team members land the flip on the same attempt.
